The Master Is the Holy Father, so I Should Be a Good Person?

Feng Yuan has traveled through time, a very classic time travel. In an ancient small village, martial arts sects and immortal sects obtain the Hunyuan Pearl, which contains a small world, and the four spiritual roots start. Well, it is obviously a mortal stream start. Just when he thought he could practice well in this world, become an immortal, and be at ease... Wait, what does it mean that my master is a complete holy father, has boundless love and wants to save all sentient beings? Why does this divine weapon have to do good things to activate, and why does this Demonic Soul Pearl emit golden light? In the end, Feng Yuan couldn't believe that in the world of scheming and cheating, he actually became a good person?
